GoBrushless Motor Kits

GBv | GBx | GBx Mini

Home-made brushless motors, also referred to as CD-ROM motors, have become very popular among electric flight enthusiasts. Why? Because they offer the performance potential found in high-priced, commercial motors without the added expense. The only problem is that finding suitable parts from salvaged CD-ROM drives is a rare occurrence, and this makes building motors with repeatable performance a near impossible task.

GoBrushless have been providing components and do-it-your self kits to US constructors for some time. The kits containing all the components needed to successfully build a brushless outrunner motor. Perhaps more importantly, the kits allow you to build as many motors as you wish, whether they're completely identical or each one is unique.

The GoBrushless web site supports a discussion forum for motor constructors and a motor performance database.


GBv 1.1
(Top | GBx | GBx Mini)

Low cost, easy to build brushless outrunner kit based on the GB 22.7mm 9-pole stator. Uses CDROM stock components and supplied with ball bearings.

New improved version is now fully assembled, magnets are glued in place, shaft is now pressed into the bell and stator is pressed on to the new aluminum bearing tube. Download the GBv tutorial.

The kit contains the following parts:

  • 22.7mm insulated stator and stock can
  • 12 of N50 5x5x1 magnets mounted into can
  • Ball bearing sleeve holder and 3mm ball bearings
  • Stock 3mm shaft
  • 3-colour set (~25 ft ea) of 26g wire

GBx Kits

The GBx kits are a GoBrushless design composed of custom-made parts to allow you to build stronger, more powerful, more efficient motors. One, two and three stator kits are available allowing you to match the motor to your aeroplane.


GBx

The GBx kit is available in one, two and three stator form and each kit contains:

  • Pre-pressed Endbell / Shaft Assembly
  • Single, Double-or Triple Stator Flux Ring
  • Aluminum Bearing Tube and 3mm Ball Bearings
  • 1, 2 or 3 22.7mm Insulated 9-pole Stators
  • 13 NdFeb N50 Magnets (5, 10 or 15)mm x 4mm x 2mm
  • Plenty of red, green and gold enamelled wire.

GBx motors are easily mounted by sliding the aluminium bearing tube into a carbon fibre tube and fixing using a small amount of epoxy or CA.

Magnets are supplied loose and are fixed into the stator using epoxy or CA. The tutorial documents explain how to do this with minimum of fuss. A template for spacing the magnets may be downloaded from the GoBrushless web site, printed onto thin card and cut out. Alternatively, a high-density reusable spacer is available - very useful if you intend making more than one motor as the card version doesn't last.

Select type:

GBx Firewall Mount

Ultra-lightweight and super-strong, the firewall motor mount sport two separate hole patterns (tapped M3.5x.5) spaced to match SP400 and SP300 mount patterns.

GBx Mini
(Top | GBv | GBx)

Quick and easy-to-build outrunner kit based on the GB� 17.8mm 9-pole stator. The #1 brushless motor kit for Cox warbirds, F3P, and indoor 3D.

Featuring state-of-the-art craftsmanship and competition-grade materials, MiniGBx. kits are the ultimate brushless outrunner kits for Cox warbirds, F3P, and indoor 3D. Sculpted around the GB 17.8mm stators, these kits are the most versatile in their league. And weighing in at as low as 11 grams, it's perfect for even your smallest aircraft.

The MiniGbx cutting-edge endbell features extremely efficient cooling and low mass, while a stepped bearing tube minimizes weight, wicks away heat, and enables drop-in replacement of any motor with an 8mm mount. Anodizing throughout for protection from the elements, high-grade ball bearings, and modular design guarantees that your motor will last a very, very long time.

Each MiniGBx kit contains:

  • 17.8mm 9-pole Stator pre-fitted to MiniGBx Bearing Tube with 1.5mm stainless steel bearings
  • MiniGBx Endbell and single flux ring with 1.5mm hardened steel shaft
  • Prop Adapter/Saver
  • 12 x N52 magnets pre-fitted to endbell/flux ring

The MiniGBx motors are pre-assembled with ball bearings and stator mounted, magnets installed, and shaft & flux ring pre-pressed. All that's left is to do the winding!
